Preparing method of low-silicon pre-melted slag for electroslag remelting

Abstract

The invention provides a preparing method of low-silicon pre-melted slag for electroslag remelting. The preparing method comprises the first step of even slag charge mixing, the second step of slag smelting and the third step of aluminum iron alloy adding and smelting. According to the preparing method of low-silicon pre-melted slag for electroslag remelting, the requirement for equipment is low, operation is easy, control is convenient, and cost is low. The problem that Al, Ti and elements prone to oxidation are burned down in the electroslag remelting process can be effectively solved.

Description

technical field

[0001] The invention relates to the technical field of preparing pre-melted slag for electroslag remelting, in particular to a method for preparing low-silicon pre-melted slag for electroslag remelting. Background technique

[0002] Pre-melted slag is an important guarantee for electroslag remelting to produce high-quality special steel and medium and high-end alloy materials. Compared with ordinary mixed slag materials for electroslag remelting, pre-melted slag has remarkable characteristics such as uniform composition, low moisture absorption rate, and low melting point. Time, to avoid phenomena such as slag collapse, thus ensuring the safety and efficiency of the electroslag remelting process. At the same time, the pre-melted slag can also effectively improve the quality of the bottom, surface and interior of the electroslag ingot, effectively reduce the hydrogen content in the electroslag ingot, significantly improve the stability of product quality and ...
